HO LDER FOR THE SETTINGS OF STONES.

SPECIFICATTION forming part of Letters Patent No. 289,106, dated November 27, 1883.

Application filed July 12. 1883. (No model.)

Toall whom it may concern.-

Be it known that I, SAMUEL JOEL, of the city and State of New York, have invented an Improved Holder for the Settings of Stones, of which the following is a specification.

The settings for precious stones are usually made from a tube of gold'or other metal, with tings are made require to be filed up and finished by engraving and other tools, and to be formed with offsets, upon which the stone rests, and with the retaining-claws to hold the stone. In doing this work by hand difficulty has arisen in holding the setting with the required firmness and in giving the necessary facility My invention relates to a holder that is ex panded within the setting and holds the same firmly upon a shoulder.

Expansible chucks and tool-holders have been made. My invention, as distinguished from these, consists in the tool having the parts hereinafter described in combination.

In the drawings, Figure 1 is an elevation.

Fig. 2 is an end View, and Fig. 3 is a section at the line a? e.

The holder for settings is made as a rod, a, preferably of steel, about four incheslong, and having a shoulder turned in the metal around the end, as at b. This shoulder is adapted to receive the base of the setting 0, and the cythe holder sufficiently far to form the ends of the holder into springs, and these are easily squeezed together by the fingers, so that the crown-setting can be placed upon the holder and rest down upon the shoulder, and the spring end is to be rendered rigid and the holder expanded firmly within the setting by a wedge or screw. I prefer to introduce the tapering pin 8 to expand the springs. This pin may be either plain on the outside or formed as a tapering screw, or else a screw may be passed through one of the spring-jaws, as seen by dotted lines in Fig. 3, and act against the other spring-jaw to expand the holder Within the setting.

I claim as my invention- The holder for settings, composed of the rod a, slotted at the end, and having a shoulder upon which the setting rests, a cylindrical portion to enter within the setting, and a wedge or screw to expand the slotted springends, substantially as set forth.

Signed by me this 20th day of June, A. D. 1883.
